The pit bull mix was found near a playground in Quincy on Aug. 31 suffering from a number of injuries.

Earlier this week, police went public with details of the abuse in an effort to find the person responsible. Since that time, the Animal Rescue League says it has seen enormous public interest in the story.

"We have been deeply moved by the outpouring of support from people all over the U.S., looking to help us identify who inflicted such pain and suffering on Puppy Doe," Mary Nee, president of the ARL said in a news release.

The ARL is accepting donations on its website to put toward the reward.
